What sign is on your treehouse?

Sometimes it just feels like the geekier corners of the internet are treehouses filled with little boys and a “no girls” sign on the door. You could maybe force your way in by pretending to be a boy, or getting their mothers involved, but it doesn’t really seem worth getting inside.

Maybe all we can do it leave them to their little treehouses, and keep building our own clubhouses with our own rules.
